I know this is not the right place to ask this, but I have posted in the TTC section and can't seem to get any replies. My LMP was around the beginning of December and as of today the 24th of January I still have not started my period. I have been having pregnancy type symptoms for almost 2 weeks now. Tender/sore breast, slight waves a nausea, very mild cramping, and of course no period. DH and I DTD on the 29th of December. I have taken a quite a few test, which all have come up negative. It's only been 3 1/2 weeks since we have done the deed. So, could it be possible that I could still be pregnant and it's just too soon to show positive yet?
